“…Vanadate crystals are widely used in solid-state diode-pumped lasers [1][2][3][4][5]. In comparison with other crystals, vanadates are characterized by a lower threshold of laser generation, higher cross-section of stimulated radiation (for example, at 1064 nm, it is 5 times higher than for Nd:YAG [5]), and wider absorption band of pumping radiation (for example, Nd : YVO 4 crystal has a pump absorption band which is approximately 4 times larger than for Nd:YAG [5]).…”

The nonlinear optical properties of a number of vanadate crystals were studied using a single-beam Z -scan at 532 nm (with a picosecond Nd:YAG laser (YAG: yttrium aluminum garnet)). Both nonlinear refraction indices and nonlinear absorption coefficients were measured for the crystals. A substantial dependence of the nonlinear optical properties of the vanadates on the cuts of the crystals, the orientation of their axes relative to the polarization vector of the laser radiation, and the ligation with active ions was observed.

“…Recently vanadate crystals have become widely used in diode-pumped lasers. In many papers, it has been shown (see, for example, [1][2][3][4][5][6]) that vanadate GdVO4, YVO 4 etc. crystals doped with rare earth elements, in particular Nd 3+ , are quite promising media for designing laser sources in the near IR range of the spectrum, including lasers based on the stimulated Raman scattering (SRS) effect for different purposes.…”

We used the single-beam Z-scan method, employing picosecond laser pulses with λ = 1064 nm, to measure the nonlinear refractive index and nonlinear absorption in vanadate crystals, which are promising for design of laser sources. We have established that there is practically no nonlinear absorption in these crystals in the near IR range and that doping them with neodymium ions leads to a significant reduction in the nonlinear refraction. This effect can be used to partially compensate for the negative impact of nonlinear refraction on the lasing characteristics of lasers.
